Instead of using the health bar from the (Non-ORK) online tutorial I want to use the default combatant HP status value as setup in the ORK tutorial.

There are no errors that pop up in the Console however I am a novice at best in coding and nothing seems to be happening in terms of my player combatant taking damage when falling from any height. I guess I am missing something.

It's pretty simple - get the combatant in a Start function (no need to do this every frame) and use the AddValue function of the status value to subtract the fall damage. I've set it up so that it ignores potential barriers :)
